I have been working in my fathers' company since 2011 as marketing, logistics and customer service manager NOC 0621, while I was still in the first college which didn't finish then switched to another college in 2015 which I finished in 2018. Then, after I have graduated in 2018 got socially secured. so my question can I claim 9 years experience; moreover, what should be written in reference letter with regard to the years before graduation. should I write part-time working for > 30 hours per week and mention that my study was full time or part-time?, I am kinda confused here and don't know what to do as the second college was right 4 years but wasn't attending lectures that much. Appreciate your favourable reply.
